In the present article, FCV was isolated more often, in terms of the overall results, but its frequency was different when the groups were analyzed separately ( Table 2) . FCV was the primary virus isolated in most of the groups examined, although FHV-1 was the virus most frequently isolated from vaccinated cats and was also isolated slightly more frequently than FCV in cats exhibiting clinical signs of disease. A greater prevalence of FCV in comparison to FHV-1 has been reported in cats with clinical manifestations of disease as well for clinically healthy cats (2, 16), although it has been shown that FHV-1 isolation is generally related to the presence of clinical signs, whereas FCV is not (12) . Furthermore, FHV-1 is the virus most commonly identified when respiratory clinical manifestations are observed (7, 13, 16, 34) ; in the present study, signs of respiratory disease were present in 24 out of the 25 sick cats from which FCV, FHV-1 or both were isolated.
